On Page 169 of the Manual there is mention of a Charging System Light ( a battery symbol) which should come on briefly at turn on. I have never seen this light in 6mths, has anyone seen this symbol ,maybe I have a blowen bulb.

I'd be interested to see him run the battery down to failure. There is nothing in this video to prove the system doesn't work. The battery wouldn't have lost much voltage, if any, during the time the vehicle was running.

I agree it's not a light that lights up when the alternator is not charging like my old kingswood but i believe things are far more advanced these days. I doubt the alternator is charging 100% of the time in the interests of fuel economy. So a light showing a drop in output of the alternator wouldnt actually help. When battery drops voltage or when a clutch engages on the alternator with no response it could still light up to provide sufficient warning. My point is this video is not providing the whole story. I haven't bothered to go right into it but it appears there IS a battery light and one might assume it will light up at some stage. Until someone conclusively proves the system is flawed I'm sceptical.
